Sensio LabsのSymfonyにおける解釈の競合に関する脆弱性

Summary

Vulnerability reported (CVE-2024-50340). Risk of unauthorized operations or information disclosure.

Original description

The description as published by the source.

SymfonyはウェブおよびコンソールアプリケーションのためのPHPフレームワークであり、再利用可能なPHPコンポーネントのセットです。バージョン5.4.46から5.4.52、6.4.40、7.4.12、および8.0.12において、CVE-2024-50340の修正は空の$_GETに対する実行時argv解析を制限しました。しかし、parse_str()とWeb SAPIは異なる動作をすることがあり、細工されたクエリ文字列によって$_GETが空のままでも$_SERVER['argv']に攻撃者が制御する--envまたは--no-debugフラグが保持されるため、APP_ENVやAPP_DEBUGが変更されてしまう可能性がありました。この問題はバージョン5.4.52、6.4.40、7.4.12、および8.0.12で修正されています。
